Aerial view of the Trans-Alaska Pipeline and Richardson Highway, looking north. Rupture along the fault resulted in approximately 2.5 meters (8 feet) displacement of the highway, with the north side moving east relative to the south side. Photo by Patty Craw, DGGS.

An aerial photo of the Trans-Alaska Pipeline System (TAPS) line near the Denali fault, looking west. This is where the line is supported by rails on which it can move freely in the event of fault offset. Here the line has moved toward the west end of the rails. Alyeska Pipeline Service Company reported no breaks to the line and therefore no loss of oil. Note the transverse crack on the Richardson Highway in lower left. Out of view to the left (south) of this photo is a 2.5 m right-lateral offset of the highway where it crosses the fault. Photo by Rod Combellick, DGGS.
